Maximum likelihood estimation
Maximum likelihood estimation (MLE) is a method of finding the parameters values that maximize the likelihood function.
For likelihood function, MLE will find the parameter to maximize :
Sometime, we transform the likelihood function with natural logarithm, for log is a strictly increasing function, we call the transformed function log-likelihood () or average log-likelihood()
If data is independent and identically distributed, the average log-likedlihood turns to
